Embodiment Construction

[0013]As utilized herein the terms “circuits” and “circuitry” refer to physical electronic components (e.g., hardware) and any software and / or firmware (“code”) which may configure the hardware, be executed by the hardware, and or otherwise be associated with the hardware. As used herein, for example, a particular processor and memory may comprise a first “circuit” when executing a first one or more lines of code and may comprise a second “circuit” when executing a second one or more lines of code. As utilized herein, “and / or” means any one or more of the items in the list joined by “and / or”. As an example, “x and / or y” means any element of the three-element set {(x), (y), (x, y)}. In other words, “x and / or y” means “one or both of x and y.” As another example, “x, y, and / or z” means any element of the seven-element set {(x), (y), (z), (x, y), (x, z), (y, z), (x, y, z)}. In other words, “x, y and / or z” means “one or more of x, y, and z.” As utilized herein, the term “exemplary” mean...

Abstract

Systems and methods are provided for a crystal (xtal) oscillator with high interference immunity. Generated reference signals may be processed to mitigate effects of interference. The processing may comprise filtering, particularly at harmonic positions, to remove or greatly reduce interference signals.

Description

CLAIM OF PRIORITY[0001]This patent application makes reference to, claims priority to and claims benefit from U.S. Provisional Patent Application Ser. No. 62 / 172,579, filed Jun. 8, 2015. The identified application is hereby incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]Aspects of the present disclosure relate to signal processing. More specifically, various implementations of the present disclosure relate to crystal (xtal) oscillator with high interference immunity.BACKGROUND[0003]Conventional approaches for utilizing crystal (xtal) oscillators (e.g., to provide clocking or other periodic signals) in electronic systems, may be costly, cumbersome, or inefficient. Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present disclosure as set forth in the remainder of the present application with reference to the drawings.BRIEF...
